I need to replace the 4 sliding pictures on [obscured] with four professional, attractive graphic slides to summarize the system as follows: 1) How the System Works, 2) Key Benefits, 3) Key Features, and 4) Testimonies

I have the bulk of the content but need to refine it and incorporate it in 4 color blending attractive graphics of the quality matching the slides being replaced but with the content specific to our software service.
